Circuit Board (PCB) Analysis

A 24-phase VRM powers the GPU, highlighted in the red rectangles above. These are controlled by a Monolithic Power Systems MP29816 controller.


All GPU power phases use Vishay SiC654A DrMOS, rated for 50 A.


Powering the GDDR7 memory chips is a 7-phase VRM driven by a uPI uP9512R controller.


Just like GPU, the memory is handled by Vishay SiC654A DrMOS chips.


The GDDR7 memory chips are made by Samsung, and bear the model number K4VAF325ZC-SC28, they are rated for 28 Gbps.


The NVIDIA GB202 GPU at the heart of the GeForce RTX 5090 is massive. It is fabricated using a 5 nanometer "NVIDIA 4N" process at TSMC Taiwan (same process as Ada). The die measures 750 mm², and comes with a transistor count of 92.2 billion.
